Synopsis: In literature and in practice, the concept of Òmental health disparitiesÓ carries with it many different (and often diverging) definitions and approaches to measurement and assessment. Based on a series of round table discussions occurring within the Minority Mental Health Interest Group (MMHI) housed at FMHI, this presentation will offer a history of mental health disparities in the United States and present various definitions of Òmental health disparitiesÓ based in the literature and round table discussions. This living/breathing presentation will also invite participation from conference attendees. The input collected from this discussion will be included in the presentation of the same focus.
